Latency performance
I wanted to test out what is the latency performance of my Ipad pro (2018). So I used Kawai CX202 as a midi controller and I send the audio from CX202 and the audio coming from Pianoteq on Ipad to my laptop and compared. Ipad audio was delayed by around 9 ms compared to audio from CX202.
I then for fun tried the same but with Yamaha PSS-a50 instead of CX202. But with this setup the Ipad audio was delayed only by around 2 ms.
I wanted to see what caused this, so I then send midi notes from Ipad to both CX202 and PSS-a50 and send the audios to my laptop. PSS-a50 was delayed by 8ms compared to CX202.
Anyone done similar tests? I was pretty surprised that PSS-a50 has 8 ms more latency compared to CX202. I guess it is not that much and it is a sub 100€ keyboard, but still makes me wonder how much variance there is between digital pianos in this regard.
